This document describes the basic features of the data.tree package. Use the data.tree package to organise hierarchical data, to write algorithms, and more. Useful for machine learning, decision trees, finance, and other applications.

Stylized example of the capabilities of the data.tree package. We implement the ID3 algorithm. The code for this document was written in less than an hour. This is possible because, thanks to the data.tree package, the implementation of the training algorithm follows the algorithm’s pseudo code almost line by line.
